Bluebeard

Dr. Seung-hoon administers a sedative to his landlord prior to a medical examination, during which the elderly man starts to recount a believable confession of murder. Not long after, the head of a young woman is found at a butcher shop owned by the landlord’s son. This discovery leads Seung-hoon to suspect that both the landlord and his son might be responsible for a series of killings.
